Schwalbe Tube SCV 17-AE Aerothan TPU 28" 33/47-622

Schwalbe Aerothan TPU Inner Tube – ultralight bicycle tube for 28 inch wheels

The Schwalbe Aerothan SCV 17-AE is a modern inner tube made of thermoplastic polyurethane (TPU). It is designed to reduce rotational weight and improve acceleration without compromising puncture protection. This tube is compatible with 28-inch tires size 33/47-622 (ETRTO) and fits tire widths from 1.3 to 1.75 inches.

• Extremely low weight of only 84 g – less rotating mass for faster acceleration and agility
• TPU material is more tear-resistant than standard butyl tubes while offering high flexibility
• Presta valve (Dunlop) 60 mm long, made of aluminum – robust and reliable
• Easy installation thanks to flexible TPU construction

What sets the Aerothan TPU tube apart

Compared to standard butyl tubes, the Aerothan saves up to 40% weight without sacrificing puncture resistance. The TPU material withstands punctures better and ages more slowly. The tube is also free of plasticizers and odorless. Its smooth surface allows easy insertion into the tire and reduces friction between tire and tube.

Ideal for...

The Aerothan is particularly suitable for road cyclists where every gram counts, as well as for sporty trekking and gravel riders who value agility and acceleration. It is also a good choice as a replacement tube for lightweight e-bikes with narrow tires.

How to use the Aerothan TPU tube

Install the tube as usual inside the tire. Make sure the valve hole in the rim is compatible with the Presta valve. Slowly inflate the tube to the recommended tire pressure (indicated on the tire sidewall). This tube is designed for clincher tires and is not suitable for tubeless systems. Store the tube dry and away from direct sunlight.
